I guess it's just a personal preference thing, really. I've certainly done my share of solo adventuring, but for Easter Island I'd prefer to run around with some company if I'm gonna' be there for several days (apparently I was mis-informed about three/four days being the minimum stay?) Plus even just for the flights, it's always fun to fly with others, especially if there are long lay-overs involved, etc.

Looking forward to it in any case!
